Question

А) -12 ∙ 29 + 17 ∙ 29; б) -458 + 415 – (48 - 458).

Answer 1

А). 1) -12*29 = -348
     2) 17*29 = 493
     3) -348+493 = 145
б). 1) 48-458 = -410
     2) -458+415 = -43
     3) -43-(-410) = -43+410 = 367

Answer 3

A) To evaluate the expression -12 * 29 + 17 * 29, we can use the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we perform the multiplication: -12 * 29 = -348. Then, we perform the second multiplication: 17 * 29 = 493. Finally, we add the two results together: -348 + 493 = 145.

Therefore, the value of -12 * 29 + 17 * 29 is 145.

B) To evaluate the expression -458 + 415 - (48 + 458), we can again use the order of operations.

First, we perform the addition inside the parentheses: (48 + 458) = 506. Then, we perform the addition and subtraction from left to right: -458 + 415 - 506 = -49 - 506 = -555.

Therefore, the value of -458 + 415 - (48 + 458) is -555.
